X87: fix the Sqrt issue. · 6a7cc6cc

weiliang.lin@intel.com authored Sep 29, 2014

The test mjsunit/regress/regress-sqrt compares the result of Math.sqrt function
when using full-compiler and crankshaft compiler seperately. But according to
glibc bug fixing(https://sourceware.org/bugzilla/show_bug.cgi?id=14032). The
glibc implementation of std::sqrt() (It is invoked in the generated code when
full-compiler is used.) will change since glibc 2.19.

In order to keep consistence of Math.sqrt translation in crankshaft compiler
and the pass of mjsunit/regress/regress-sqrt. we translate the Math.sqrt func
by calling the runtime function.
